Method for determining the presence of an aminotransferase (AT1), other than aspartate aminotransferase (AST), in a biological sample. The method includes contacting the sample with an amino donor substrate for AT1, an amino acceptor substrate for AT1, cysteine sulfinic acid (CSA) in excess, a second aminotransferase (AT2), different from AT1, in excess, and an indicator for the presence of sulfite ions, under conditions in which the concentration of said AT1 can be determined by the amount of the indicator which forms a detectable signal. |
